I have never made one of these, but looking online, they look pretty simple to create. There are a lot of PowerPoint templates online. Check out this page.

https://www.smaply.com/templates – This one has a PDF that you could place into InDesign and then re-create.

Not an InDesign template, but you could re-create it pretty easily in InDesign. Mostly a table set up with columns.

As a workaround – can you just make it link to another page (with items spec sheet) at the end of your document instead of a pop-up window?

Did you ever get this to work?

1. On button info, choose Event: On Roll Over, make a text box visible and then choose Event: On Roll Off, make a text box not visible. This toggles between showing and not showing.

2. You either have to choose text and make a hyperlink in Indesign under Interactive panel before making PDF, or add it after it is a PDF in Adobe Acrobat Pro (under Content > Add or Edit Ineractive Object > Link and then draw a box around item, choose Open a Web Page and then add URL.

3.The button usually has to have an Action added in InDesign. Choose button and on Buttons/Forms panel, with Event: On Release or Tap, add an Action of Go to Next Page. Then when you make PDF, it will do so.

Hope this helps.
